In this embodiment, a device wake-up method is provided, and fig. 2 is a flowchart of the device wake-up method according to the embodiment of the present invention, where the flowchart includes the following steps:
step S202, obtaining wake-up parameter values uploaded by a plurality of devices after receiving wake-up voices of target objects, wherein the wake-up parameter values include at least one of the following: the device determines a distributed characteristic value according to the awakening voice and a direction value according to the awakening voice, wherein the distributed characteristic value is used for indicating an attenuation value of the awakening voice after the awakening voice is transmitted between a target object and the device through a spatial distance, and the direction value is used for indicating an included angle which is in accordance with a preset range between the forward direction of the device and the target object which emits the awakening voice;
step S204, under the condition that at least one group of awakening parameter values corresponding to each device in a plurality of devices are obtained, respectively carrying out weighted calculation on all awakening parameter values corresponding to each device so as to determine the awakening values corresponding to each device;
step S206, determining a target wake-up value meeting a preset condition from the plurality of wake-up values, and waking up a target device corresponding to the target wake-up value.
Through the steps S202 to S206, wake-up parameter values uploaded by the multiple devices after receiving the wake-up voice of the target object are obtained, where the wake-up parameter values include at least one of the following: the device determines a distributed characteristic value according to the awakening voice and a direction value according to the awakening voice, wherein the distributed characteristic value is used for indicating an attenuation value of the awakening voice after the awakening voice is transmitted between a target object and the device through a spatial distance, and the direction value is used for indicating an included angle which is in accordance with a preset range between the forward direction of the device and the target object which emits the awakening voice; under the condition that at least one group of awakening parameter values corresponding to each device in a plurality of devices are obtained, respectively carrying out weighted calculation on all awakening parameter values corresponding to each device so as to determine the awakening values corresponding to each device; and determining a target awakening value meeting a preset condition from the plurality of awakening values, and awakening the target equipment corresponding to the target awakening value. Even if the awakening design based on the distributed mode is used, the corresponding equipment awakening value is determined according to the distance between the user and the equipment and the orientation of the equipment, so that the equipment needing to be awakened is determined, the problems that in the related technology, the awakening voice can awaken a plurality of pieces of equipment and the like are solved, the pertinence of awakening the equipment by using the awakening voice is improved, the trouble that the equipment responds to the awakening voice at the same time is reduced, and the 'one-hundred-call' scene is avoided.
It should be noted that the distributed eigenvalues and orientation values are generated according to the condition of the wake-up voice acquired by the device, namely, after the equipment receives the related awakening voice, the equipment compares the current awakening voice with the standard awakening voice set by the user when the equipment is started through a preset algorithm in the equipment to confirm the attenuation condition of the voice, obtaining distributed characteristic values of the current awakening voice, wherein the orientation value is used for distinguishing the devices in the uniform position from different devices to be awakened, which is used to indicate the included angle between the forward direction of the device and the target object which emits the wake-up voice, which is in accordance with the preset range, preferably, the included angle of the preset range in the invention is 0-180 degrees of the forward direction of the equipment, and when the included angle is beyond the range, the orientation value of the wake-up parameter value uploaded by the device after receiving the wake-up voice of the target object is correspondingly 0, that is, the cloud distribution service performs weighted calculation with the orientation value of the device as 0.
For example, if the television device faces south, the speaker stands on the back of the television, and if there is a speaker next to the television, the television will not be woken up because the front of the television device faces more than 90 degrees, and because the speaker faces all around, it is calculated that the speaker and the speaker face smaller, so the speaker is woken up preferentially, and the television is not woken up.
In an optional embodiment, after obtaining wake parameter values uploaded by a plurality of devices after receiving the wake speech of the target object, the method further includes: determining the number of the plurality of devices bound with the target object; when the number of the devices is greater than a target number, determining a difference value between the distributed characteristic value of each device in the number of the devices and a maximum distributed characteristic value, and performing device awakening suppression on the device corresponding to the difference value exceeding a preset difference value range, wherein the target number is an integer greater than 1, and the maximum distributed characteristic value is a maximum value among a plurality of distributed characteristic values uploaded by the devices.
In short, after acquiring a plurality of distributed eigenvalues and a plurality of orientation values uploaded by a plurality of devices, the number of devices bound by a target object needs to be determined, and when the number exceeds the target number, a difference value between the distributed eigenvalue of each device and the maximum distributed eigenvalue is calculated, and a device corresponding to the out-of-range difference value in the calculated plurality of difference values is suppressed and awakened according to a preset difference value range.
In an optional embodiment, acquiring wake-up parameter values uploaded by a plurality of devices after receiving a wake-up voice of a target object includes: and acquiring a wake-up parameter value determined by the equipment according to a distributed session message, wherein the distributed session message is determined according to an analysis result, and the analysis result is an analysis result obtained after a software development kit on the equipment analyzes the wake-up voice. In short, after the device to be awakened receives the awakening voice of the target object, the awakening voice is analyzed, the distributed session message in the awakening voice is confirmed, and then the distributed characteristic value and the orientation value of the current device based on the voice awakening are obtained through the operation of the voice awakening algorithm in the device according to the distributed session message.
In an optional embodiment, after obtaining wake parameter values uploaded by a plurality of devices after receiving the wake speech of the target object, the method further includes: acquiring a preset threshold range of the awakening parameter value; determining a size relationship between a wake-up parameter value of each of the plurality of devices and the preset threshold range; and removing the equipment corresponding to the awakening parameter value exceeding the preset threshold range from the awakening alternative list so as to determine the target awakening alternative list meeting the preset threshold range.
That is to say, according to the preset threshold range of the wake-up parameter values set in the cloud distributed service, multiple sets of wake-up parameter values of multiple currently acquired devices can be screened, and the devices corresponding to the wake-up parameter values which do not meet the preset threshold range are moved out of the wake-up candidate list, so that the occurrence of uploading the devices to be wakened which do not meet the preset threshold range is reduced.
In an exemplary embodiment, determining a target wake-up value meeting a preset condition from a plurality of wake-up values, and waking up a target device corresponding to the target wake-up value includes: executing a distributed decision on the plurality of wake-up values, wherein the distributed decision is used for determining the wake-up values meeting preset conditions; obtaining a decision result of the distributed decision to determine the target wake-up value; and sending a wakeup indication to the target equipment corresponding to the target wakeup value in a target period to indicate the target equipment to perform wakeup.
For example, when a user sends a wakeup voice in a living room, the multiple devices upload distributed characteristic values and orientation values obtained by the device operation to the cloud distributed service according to the received wakeup voice, and then the cloud distributed service performs weighted calculation on multiple groups of wakeup parameter values (namely the distributed characteristic values and the orientation values) corresponding to the multiple devices to obtain multiple wakeup values corresponding to the multiple devices.
In an optional embodiment, after the step S206, the method further includes: acquiring a preset awakening time interval, wherein the preset awakening time interval is used for indicating a time range allowing continuous awakening among a plurality of awakening voices; when the target wake-up time interval among the plurality of wake-up voices exceeds a preset wake-up time interval, setting a silent parameter value of a first wake-up voice which reaches the equipment at first to be false, and setting a silent parameter value of a second wake-up voice which follows the first wake-up voice to be true, wherein when the silent parameter value is false, the wake-up voice is normally awakened to the equipment, and when the silent parameter value is true, the wake-up voice is not awakened to the equipment.
The target object may send a plurality of wake-up voices in a short time, in order to wake up the device, and in order to avoid that the same device is awakened for multiple times to perform device response broadcast, the target object is disturbed, so that after the current device is determined to be awakened, a preset wake-up time interval may be obtained, and when the target wake-up time interval between a plurality of wake-up voices exceeds the preset wake-up time interval, the wake-up voice after the first wake-up voice successfully waking up the device cannot wake up the device.
In an optional embodiment, after setting a silence parameter value of a first wake-up voice which reaches a device first to be false and setting a silence parameter value of a second wake-up voice which follows the first wake-up voice to be true, the method further includes: acquiring the silence parameter value in a plurality of wake-up voices; and sending a response instruction for broadcasting response content to the terminal according to the silence parameter value, wherein the response instruction is used for indicating that the voice awakening device is successfully awakened when the silence parameter value is false in the plurality of response results.
In short, in order to better inform that the target device corresponding to the target object has been successfully awakened by the awakening voice, a response instruction is sent to the terminal according to the obtained silent parameter value, and the terminal is instructed to perform awakened broadcasting on the awakening voice awakening successful device with the false silent parameter value in the plurality of response results.

step S9, issuing a distributed decision 300ms result;
step S10, calling back the distributed result;
step S11, the sound box plays a prompt tone;
step S12, starting ASR (Automatic Speech Recognition, ASR for short);
step S13, voice interactive conversation;
step S14, distributed continuous decision is issued;
step S15, calling back the distributed continuous result;
step S16, the sound box is silent or continues to recognize the conversation;
step S17, the voice service acquires a distributed result;
step S18, sending down a voice result including a distributed decision result;
step S19, calling back the voice result;
and step S20, the sound box silences or executes the intention according to the semantic result.
Specifically, the cloud receives a distributed wake-up request of the device. And in the same family, if only one device exists in the family, sending an instruction of agreeing to wake up to the device. In the same family, if a plurality of devices exist in the family, if the current device is the first device participating in voice request awakening, the characteristic value of the device is used as the maximum characteristic value of the awakening in the current round, the time millisecond number when the request arrives is recorded, and the cache list is emptied. If the current equipment is not the first equipment participating in the distributed voice request awakening, calculating the characteristic value of the current equipment and the maximum characteristic value of the current round, and if the difference value exceeds a specified range, sending an awakening inhibition instruction to the equipment. If the gap is small, the device characteristics are cached. Further, the wake-up request of the device continues to be received until 200 milliseconds. If only 1 device exists in the cache list, a command of agreeing to wake up is sent to the only device in the cache list. When the number of records in the list is more than 1, the characteristic values and orientation values of the devices in the cache list are calculated in a weighted mode, the device corresponding to the wake-up value with the largest score is the device to be woken up, then a command for agreeing to wake-up is sent to the device corresponding to the wake-up value with the largest score in the cache list, and a command for inhibiting wake-up is sent to the devices except the device corresponding to the wake-up value with the largest score; subsequent requests by the voice device are received until the maximum time allowed for distributed wake up is exceeded for 4 seconds. Modifying the response of the first arriving device request, accompanied by a silence parameter value set to false; the subsequent device request reply is accompanied by a silence parameter value set to true. And the terminal determines whether to broadcast the content according to the silence parameter value. The maximum eigenvalue is also the aforementioned distributed eigenvalue.
As an optional implementation manner, the cloud distributed wake-up service receives a wake-up request of the terminal device within 200 milliseconds, and decides which devices stop picking up sound or not according to the size of the distributed eigenvalues uploaded by the devices. If the difference of the characteristic values of the plurality of devices is within a specific range, a decision is made according to the comparison orientation. The eigenvalue is large, speech interaction continues towards more reasonable equipment, and other equipment stops picking up sound. In consideration of performance difference and network reasons of the equipment, the cloud distributed service continuously receives a newly-added equipment awakening request within 4 seconds, compares a new request characteristic value and orientation with a current equipment characteristic value and orientation, leaves the equipment with a large characteristic value and a more reasonable orientation to continue voice service, and stops sound pickup of other equipment. The orientation is the angle between the human face and the forward direction of the device. If the television equipment faces south, the speaker stands on the back of the television, if a sound box is arranged beside the television, the television should not be awakened at this time because the orientation exceeds 90 degrees, and because the orientation of the sound box is omnibearing around, the orientation of the speaker and the sound box is calculated to be smaller, so that the sound box is preferentially awakened, and the television is not awakened. In the voice recognition stage, if multiple devices return a voice recognition result, the suppressed devices stop broadcasting voice according to the processing result of the current cloud distributed service in the wake-up stage.
Through the optional embodiment, which equipment stops picking up sound is determined according to the characteristic value and the orientation value of the voice, a unique piece is left for conversation and voice broadcasting, and the problem that a plurality of pieces of equipment in the same family sense the voice of the user and report the voice processing result to cause that the user cannot hear the voice is solved. And then when making equipment increase, also can determine the optimal equipment when carrying out equipment and awaken up, can discern the online equipment simultaneously under the same family name, can let that audio amplifier or equipment that is closest to the user handle user's pronunciation to answer, promoted the user and experienced to the voice interaction of equipment.

Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
In this embodiment, an apparatus wake-up device is further provided, and the apparatus is used to implement the foregoing embodiments and preferred embodiments, which have already been described and are not described again. As used below, the term "module" may be a combination of software and/or hardware that implements a predetermined function. Although the means described in the embodiments below are preferably implemented in software, an implementation in hardware, or a combination of software and hardware is also possible and contemplated.
Fig. 4 is a block diagram of a device wake-up apparatus according to an embodiment of the present invention, and as shown in fig. 4, the apparatus includes:
an obtaining module 42, configured to obtain wake-up parameter values uploaded by multiple devices after receiving wake-up voices of a target object, where the wake-up parameter values include at least one of: the device determines a distributed characteristic value according to the awakening voice and a direction value according to the awakening voice, wherein the distributed characteristic value is used for indicating an attenuation value of the awakening voice after the awakening voice is transmitted between a target object and the device through a spatial distance, and the direction value is used for indicating an included angle which is in accordance with a preset range between the forward direction of the device and the target object which emits the awakening voice;
a determining module 44, configured to, when at least one group of wake-up parameter values corresponding to each device in the multiple devices is obtained, perform weighted calculation on all wake-up parameter values corresponding to each device, respectively, to determine a wake-up value corresponding to each device;
and a wake-up module 46, configured to determine a target wake-up value meeting a preset condition from the plurality of wake-up values, and wake up a target device corresponding to the target wake-up value.

It should be noted that the distributed eigenvalues and orientation values are generated according to the condition of the wake-up voice acquired by the device, namely, after the equipment receives the related awakening voice, the equipment compares the current awakening voice with the standard awakening voice set by the user when the equipment is started through a preset algorithm in the equipment to confirm the attenuation condition of the voice, obtaining distributed characteristic values of the current awakening voice, wherein the orientation value is used for distinguishing the devices in the uniform position from different devices to be awakened, which is used to indicate the included angle between the forward direction of the device and the target object which emits the wake-up voice, which is in accordance with the preset range, preferably, the included angle of the preset range in the invention is 0-180 degrees of the forward direction of the equipment, and when the included angle is beyond the range, the orientation value of the wake-up parameter value uploaded by the device after receiving the wake-up voice of the target object is correspondingly 0, that is, the cloud distribution service performs weighted calculation with the orientation value of the device as 0.
For example, if the television device faces south, the speaker stands on the back of the television, and if there is a speaker next to the television, the television will not be woken up because the front of the television device faces more than 90 degrees, and because the speaker faces all around, it is calculated that the speaker and the speaker face smaller, so the speaker is woken up preferentially, and the television is not woken up.
